Hi!
I'm beginner in Linux and ask for support in first installation.
I got the old Compaq Armada 1130T sligtly upgrated:
- Petnium 120 MHz
- 48 M RAM (extended)
- 6.5 G HD (extended, empty)
- FDD
- no CD
- PCMCIA LAN card by Compex.
My intention was to install Stable Debian by net installation with floppy installer.
Last 2 days all my attempts to start installation faced the same result:

Press F1 for help, or ENTER to boot:
Loading Linux...................
Loading initrd.gz....
At that point all hangs up.

Could you advice what shall I do to proceede with installation, please.
